Abstract

Ensemble pompe (1, 33, 200) conçu pour pomper du sang en continu. Dans un mode de réalisation spécifique, la pompe (1, 200) est une pompe centrifuge dans laquelle la roue (100, 204) loge de façon étanche à l'intérieur du carter (2, 201) et est suspendue de façon exclusivement hydrodynamique dans ledit carter simultanément à sa rotation à l'intérieur du liquide (105) poussé par des moyens électromagnétiques extérieurs à la cavité de pompe (106, 203). Les déformités, telles que des ailettes (8) dont les surfaces se rétrécissent depuis les bords avant (102, 223) jusqu'aux bords arrières (103, 224) des surfaces inférieure et supérieure (221, 222) de la roue (100, 204), contribuent à la suspension hydrodynamique de cette dernière. L'invention concerne également un système d'évaluation et de commande de l'ensemble pompe (1, 33, 200).
